mmm...I'm not so sure Gaza. That's a very big gesture by BA. Giving free flights to those involved in Concorde's return is a costly venture (100 seats which it could retail at £8000+ a seat)...why not just give them all a nice big bonus?
Also, using BA staff to test the Concorde product is a false experiment, as most of these staff will not have experienced the Concorde product in the past so there is no opportunity for comparison.
I'll be interested to see how BA spin these proving flights.
